IMPROVEMENT IN N'AILS.

Specification formn g part of Letters Patent No. 135,114, dated JanuaryQ1, 1873.

To all whom it may concern:

Be it known that I, WILLIAM N. HALL, of Mexia, in the county ofLimestone and State of Texas, have invented a certain new and usefulImprovement in the Manufacture of Nails, of which the following is aspecification:

My invention consists of a new article of manufacture and trade, being anail of hexagonal form, the part whereof near the head having two sidesnearly dat, with beveled edges, and the slant or bevel toward the pointor inserting-end on each side at right angles to the said iattenedbeveled sides, so as to approach a chisel-point, merging into sharpopposite edges, the advantages of which will be hereinafter more fullydescribed.

In the accompanying drawing, Figure 1 represents views, in elevation, ofmy improved nail; and Fig. 2 represents views in section of the same,taken, respectively, in lines cc m and y y of Fig. 1.

The drawing 'represents a full-sized sixpenny nail 7 made in accordancewith my invention.v The nail is made by having two of its sides abeveled to form sharp edges about two-thirds of its length, as shown atb, and in beveling the edges thus formed at right angles, so as toapproach a chisel-point, as shown at c in Fig. 1 of the drawing. Thusformed, the nail has a taper from its point to its head, whereby thegreatest wedgng is exerted in the first stages of driving, and decreasesas it proceeds; hence there is scarcely any liability to split the wood.In an enlarged view I have shown, at c', the manner in which the bevelsc have a sharper bevel to form a stout point, whereby I avoid theliability of thenail to break.

It will thus be seen that my improved nail has its two sides decreasingand tapering from the point to the head 5 that these sides have theiredges beveled; that these beveled edges are intersected, at aboutone-third of the length of the nail from its point, with bevels at rightangles thereto, ending in the stout point above described. This point clwill cut its way into the hardest wood Without breaking, and forordinary purposes the nail may be made of cheaper and inferior iron tothat now used.

The several oblique edges and tapers of the nail form holding-shoulders,which give to the nail a most tenacious hold upon the wood. Havingdescribed my invention, I claim- The nail, substantially as hereindescribed, as a new article of manufacture and trade.

In testimony whereof I have hereunto set my hand this 23d day ofOctober, A. D. 1872.

- WILLIAM N. HALL.
